Summary: This document is ready with minor issues.



Major issues:



None



Minor issues:



1.



The text in the second and third paragraphs in section 2.2 is rather confusing.
Do these belong to updates, or should they be under Notes?



Ø



Admittedly, the NAT has to verify whether received TCP RST packets belong to a
connection. This verification check is required to avoid off-path attacks.



Ø



If the NAT removes immediately the NAT mapping upon receipt of a TCP RST
message, stale connections may be maintained by endpoints if the first RST
message is lost between the NAT and the recipient.



If they belong to Updates ‘Admittedly’ needs to be dropped, ‘has to verify’
becomes ‘SHOULD verify’, etc.

Else, if these are rather notes they should be labeled Notes or Clarification



[Med] These are notes. What about making this change?



OLD:



      Admittedly, the NAT has to verify whether received TCP RST packets

      belong to a connection.  This verification check is required to

      avoid off-path attacks.



      If the NAT removes immediately the NAT mapping upon receipt of a

      TCP RST message, stale connections may be maintained by endpoints

      if the first RST message is lost between the NAT and the



recipient.



NEW:



      Notes:

      *   Admittedly, the NAT has to verify whether received TCP RST packets

      belong to a connection.  This verification check is required to

      avoid off-path attacks.



      * If the NAT removes immediately the NAT mapping upon receipt of a

      TCP RST message, stale connections may be maintained by endpoints

      if the first RST message is lost between the NAT and the



recipient.







2.



In section 5:



Ø



This update is compliant with the stateful NAT64 [RFC6146] that clearly
specifies three binding information bases (TCP, UDP, ICMP).



As the focus of this document is NAT44, I do not believe that ‘compliant’ is
the right word. Probably ‘consistent’ would be more appropriate.



[Med] I changed it to “consistent” in my local copy. Thank you for catching
this.



3.



EIF is never expanded

[Med] Fixed.



Nits/editorial comments:



None.
